ConAgra Foods is to break ground on a $100 million expansion to a plant in Russellville where it plans to add 80 new jobs.

The ceremony is set for 10 a.m. Friday to mark the addition.

Omaha, Neb.-based ConAgra announced the expansion last year. It plans to produce Bertolli and P.F. Chang's frozen meals at the facility. The company acquired these brands last year as part of its effort to devote more of its business to frozen foods.

The Russellville facility has been in operation since 1964, and produces Banquet, Healthy Choice and Marie Callender's products.

ConAgra is also known for making Slim Jim snacks and Peter Pan peanut butter.
